Non-Violent, Disruptive Protest. The Vice President for Student Life or his/her designee will go to the area and ask the protestors to leave or to discontinue the disruptive activities. âI am _________________, speaking on behalf of the University of Iowa.
Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.
Control losses occur on the discharge side of a centrifugal pump that has been equipped with a backpressure valve to control flow rate. As the liquid flows through the control valve, energy is lost. Next to static head, control losses are frequently the most important factor in calculating the pumpâs total dynamic head. pump can be defined as âa mechanical device that adds energy to a fluid to increase its flow rate and static pressure.â This process can be accomplished with positive displacement pumps or kinetic-energy pumps.
